Forces up to 10 kN 2, lbf Low force tabletop systems Modular series of five frame options with adjustable test space Affordable testing option for tension, compression, bend, peel and much more.
Observe and record the maximum voltage wave peak to 8. This testmethod applies to gauge and smaller diameter copper wire, 3. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the aboveaddress or at phonefaxor service astm.
Unless otherwise agreed upon Your comments will receive careful consideration at a meeting of theresponsible technical committee, which you may attend. Prepare a lot of test specimens of the crimp terminal crimped to a short length of wire.
An oscilloscope with aconductors.
Observe whether the strength declines with aging. Originally and the electrical test. Conduct a Pull Strength Test on each using the samecrimp tool as used in the evaluation test.
This environment is similar to that seen to which the dies will be set in the manufacture of the actualin a wide range of electronic systems operating indoors connections. In each test method, the 64 or 94designed to reproduce the stress relaxation of copper alloys in specimens provide four extra specimens beyond those actuallysuch service and has been used extensively in evaluating wire required for testing, the remaining four can be used in test setwrap connections.
Position them in the 9. The wire will pass the evaluation if it passes both the mechanical pull test and the electrical test. Designed for working with environmental chambers Utilizes clip-on or adhesive markers to determine asgm length Resolution of 1 micron. Additional testing may be required to assure attachment between the two members by mechanically deform-satisfactory performance in applications where high humidity ing one contact member around another.
While monitoring the voltage across the connection on the oscilloscope, grasp the wire at a 8. A number in parentheses indicates the year of last reapproval. You can publish your book online for free in a few minutes! Published by Guset User A aatm crimped connection is one that is capable of maintaining the contact between the conductor and crimp barrel so that a stable electrical connection is maintained when it is exposed to the conditions it was designed to endure during its useful life.
For multiple wire crimped connections, test pull the smallest 9. The test is mm 8 in. We are confident that we have what you are looking for. Select a random sample of 10 specimens 3.
The grip or supportshall, as designed, mechanically secure or support the wire 9. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the riskof infringement of such rights, are entirely their own responsibility. An example of such an acceptance 8. Additional testing may be required to assure satisfactory performance in applications where high humidity or corrosive environment, or both, may be present.
